Digital Lux Meter

Product Details:

• Light-measuring levels ranging form 0.01lux~0.1klux/0.01fc~0.01kfc,repeatedly.
• High accuracy and rapid response.
• Data-hold function for holding measuring values.
• Unit and sign display for easy reading.
• Automatic zeroing.
• Meter corrected for spectral relative efficiency.
• Correction factor need not be manually calculated for non- standard light sources.
• Short rise and fall times.
• Peak-hold function for tracing the peak signal of light pulse with least duration 10μs and store it.
• Capable of selecting measuring mode in lux or fc scale alternatively.
• Auto power off 30 minutes.
• Maximum and minimum measurements.
• Relative reading & Reset function.
• Easy to read large backlit display
